6.2.1Conducted noise immunity
Noise is specified as a periodic and random distribution of frequencies covering a band from DC to 10 MHz. Maximum allowed noise values given below are
+5V | = | 250 mV pp from 0 to | 100 kHz to 20 MHz. |
+12V | = | 800 mV pp from 100 | Hz to 8 KHz. |
|
| 450 mV pp from 8 KHz to 20 KHz. | |
|
| 250 mV pp from 20 KHz to 5 MHz. |
6.2.2Power sequencing
The drive does not require power sequencing. The drive protects against inadvertent writing during
6.2.3Current profiles
The +12V and +5V current profiles are shown below in the following figures.
Note: All times and currents are typical. See Tables 12, 14, and 16 for maximum current requirements.
